This circuit is a temperature sensing as well as alarm circuit. The circuit raises an alarm whenever the temperature crosses a certain limit. This circuit is a temperature sensing as well as alarm ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

You can use an ADT7461 single-channel temperature monitor, an ADG708 low-voltage, low-leakage CMOS 8-to-1 multiplexer, and three standard 2N3906 pnp transistors to measure the temperatures of three ...

Each sensor costs $39, or you can pick up a three-pack for $99 for people who actually own houses large enough to need that many independently temperature-monitored rooms. (I live in an apartment, so ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...
